"We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey
Christ . . . " (ESV)
Behold the work of the Christian ministry: it tears down, so that it can build up (see v. 8). Jesus did this. He came and destroyed the prevailing notions of God and His worship; and then set up the way of the Kingdom (church)--which is glory achieved through suffering, or the cross leading to the resurrection.
A faithful ministry will sometimes make us a bit ill at ease, and always with regard to our favorite sins--especially those that are cloaked in religion. But, let us be encouraged: those who respond well will be abundantly recompensed, with a quiet conscience and a joyful heart.
[Puritan quote of the day: "Tender consciences have their hearts smitten for little sins. . . . Those sins that almost break a godly man's heart never break a wicked man's sleep." --Christopher Love, in "The Mortified Christian"]
